FLASH-LIGHT nrrnnne'ros.

Anplication filed October 22, 1821.

To (171 n /mm. it may concern.

be it known that I. Evnnnnn L. JonNsoN, a eitizen ol' the United States,and residing at l atrhogiw. L. 1.. in the county of Suffolk and f tuteof New York. have invented certain new and useful Improvements in Flash-Light iipparalus, of which the following a suecilication. such as willenable those skilled in the art to which it appertains to make and usethe same.

This invention relates to tlasl'l-light apparatus and particularly tothe tlash bag or .aldnet of apparatus oi this class. and the object. ofthe invention is to provide an improved bag supporting frame which is soennstructed as to permit of the 't'olding or rolla 'isingg; oi saidi'rameivork and the extension oi the same into an oblong position;

a further objert being to provide means for 7 receiving and reniovinnthe dust or ash ot the explosive medium employed and which collects insaid flash bag or cabinet; and llll these and other objects in view theinvention consists in an improved apparatus ol' the Mass r-ipeeilied\vhioh is simple in instruction and etlirient in mean and which iseonstru -ted as lu-reinatter described and r lainled.

The iinention l'ully disi'losed in the following; speeiiieution, oiwhich the illft'fllllpanyirn; drawing;- forms a part. in Which theseparate parts ot my improvement are designated by suitable referencecharm-tors in each of the views. and in which Fig. l is a back view ofthe bag or cabinet showingthe framework thereof in an extended position;

Fig. 2' a partial section on the line a ain Fig. 1;

Fig. 3 a plan view of the construction shown in Fig. i;

Fig. 4 a view similar to Fig. l but showng; the parts in a differentposition and \i iih part ot the construction emitted;

Fig. 3 a partial section on the line .ii ol' Fig. l on an enlargedscale: and

Fig. {3 :1 partial section on the line (i t; ot' Fig. 2 on an enlargedscale.

in the drav-iinu' l have shown at 10 a fla h bag; or cabinet toinposedof our suitable flexible fireproof material. and said has. in thei-onstruetion shown. is approximately triangular in term in crosssection and romprising a back wall 11. a top will 12. side Serial No.509,673.

Walls 13 and an angularly arranged front Wall 14. the bottom edges ofthe back wall 11 and front wall 1.4-. are secured to a longitudinal base15 provided With an a ertilre 16 which opens upwardl into the ag 10 andoutwardly through tie bottom of said base, and a suitable shutter device17 mounted inthe base 15 is adapted to normally close the aperture 16,said shutter being operated by means of a crank 18 extendin through oneend Wall of the base 15. as shown in Fig. 6. The base 15 is providedwith a removable cover plate 19 secured in position by catch or hookdevices 20 at the ends thereof, and said cover plate is provided with anaperture 21 which registors with the aperture 16 in the base 15. and thebottom of the rover late 20 is pro vided with a sack 22 preferab ycomposed of flexible material.

The bag 10 is adapted to be supported in the position shown in Figs. 1,2 and 3 of the drawing; by a suitable framework 23 vomprising, in the(:onstruetion shown. 1 central frame member a top frame member 2.1 and abottom frame member 2(5. The frame members 24, 25 and 26 extendlongitudinally of the back wall ll of the but: when in use, and saidbank wall is secured thereto, and the bottom member 26. in theconstruction shown, is formed by the base .15 of the bag 10, and twomovahl frame members 27 are pivotalhmounted in connection with the framemember 26 or base 15 as shown at 28 and are adapted to be extendedvertically at the opposite sides or' the frame 23 and to be held in suehposition by clamps 29 which frietionally engage said frame members 27,and said clamps are operated by milled nuts 30 mounted on pins orbolts31 secured or mounted in the end portions of the frame members 2 1- and25.

The upper edge of the front wall it of the bag il and the front edge ofthe to vvall l2 thereof are secured to a strip 31. 'lll('ll extendslongitudinally of the bag and brace rods 33 are preferably arranged inthe manner shown in Fig, I of the drawing. and the e rods serve tosuJport the strip 32 in proper position. to hold the Front wall H- ofthe bag it) in a taut or drawn posh lion. and by a"i|is'ting the framemember 2-1 and 23 vertieali r on the frame members QT the bark all 11 ofthe bag may he also drawn aml held in a taut position.

The central frame memher 24 of the frame 23 is enlarged centrallythereof as shown at I36 an l provided with a door 37 which normally(loses an opening in the enlargement 536 of the frame 24. and thistltPOI' PH'ITliiIS of the phu'rment of the expioaire medium employed inapparatus of this if so in proper position on a. tlanh gnu, of any himlor Class. sueh as USHHllIV employed in apparatus of this ines, and atripod or other support may he eonneeted with a. her-per 39 on theenlargement 36 of the frame member 2 1 for supporting the ha; and theframmrm'lt thereof in a predetermined 'iosition relative to a floor orin a. room or eompartnwnt.

It will he apparent that by loosening the. winged nuts 30. the framememhera .24 and '33 may he dropped downwardly an-.l the frame memhera 2Tmover into a horizontal position as shown in Fig. 1 of the draw ing, andthe hraee rods 3 may be detached from the keepers 34- antl the. strip 32IIli'iCQ-il into juxtaposit on to the top frame. meniher "25 asindicated in dotted lines in Fin. 3. and the hraee ItNlQ 33 folded intoan apgu'oximate parallel position to SiliKl strip.
